Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a thermoplastic resin plate is used for fire-resistant plates or end plates, then ease of manufacture is improved, but heat resistance is insufficient
Solution Approach 1:
The patent changes the material parameter from thermoplastic resin to thermosetting resin composition, which fundamentally alters the thermal properties. The thermosetting resin undergoes curing to form a cross-linked structure that provides superior heat resistance while maintaining manufacturability through casting or molding processes.
Solution Approach 2:
The patent uses a composite material system consisting of thermosetting resin composition that combines the benefits of fire resistance, heat resistance, and thermal insulation. The cured product of the thermosetting resin creates a composite structure that satisfies multiple performance requirements simultaneously.
2Temperature
If a metal plate is used for fire-resistant plates or end plates, then heat resistance is improved, but thermal insulation deteriorates
Solution Approach 1:
The patent changes the material from metal to thermosetting resin, fundamentally altering the thermal conductivity parameter. The cured thermosetting resin composition provides low thermal conductivity, achieving both heat resistance and thermal insulation properties that metal cannot simultaneously provide.
Solution Approach 2:
The thermosetting resin composition creates a composite material structure that inherently provides thermal insulation while maintaining fire resistance. The cross-linked polymer matrix and potential filler materials work together to reduce heat transfer while withstanding high temperatures.
3Temperature
If a cured product of thermosetting resin composition is used for fire-resistant plates or end plates, then heat resistance and thermal insulation are improved, but weight increases compared to metal plates
Solution Approach 1:
The patent employs composite material technology where the thermosetting resin composition can be formulated with lightweight fillers or reinforced with fibers to achieve high strength-to-weight ratio. The cured product provides the necessary mechanical strength and thermal performance while remaining lighter than solid metal plates.
Solution Approach 2:
The patent applies the thermosetting resin composition specifically where thermal insulation and fire resistance are most critical, rather than using heavy metal throughout the entire battery module structure. This localized application optimizes weight while maintaining necessary performance.
4Object-affected harmful factors
If a cured product of thermosetting resin composition is used for fire-resistant plates or end plates, then fire prevention is improved, but rigidity may be reduced compared to metal plates
Solution Approach 1:
The thermosetting resin composition is formulated as a composite material that incorporates reinforcing fibers or fillers to enhance rigidity and mechanical strength. The cross-linked polymer matrix provides fire resistance while the reinforcement structure maintains the necessary structural rigidity for battery module support.
Solution Approach 2:
The patent modifies the physical and chemical parameters of the thermosetting resin composition, including cross-linking density, filler content, and reinforcement structure, to optimize the balance between fire resistance and mechanical rigidity for the specific application requirements.
